Eyeglasses correct four main vision problems:

There are four vision deficiencies for which eyeglasses can compensate. Nearsightedness (myopia) is a vision disorder that causes far objects to appear blurred but near objects are seen clearly. Corrective eyeglasses with concave (inwardly curved) lenses compensate for the refraction error by moving the image of a distant object backward onto the retina Farsightedness (hyperopia) is a condition that allows far objects to be seen clearly but presents difficulty with near vision. Corrective eyeglasses with convex (outwardly curved) lenses compensate for the refraction errors by moving the image of a distant object forward onto the retina. Astigmatism is a vision disorder caused by a non-uniform curvature in the refractive surfaces of the eye. Light rays do not all come to a single focal point on the retina, some focus on the retina while others focus in front or behind it. This condition can occur in conjunction with nearsightedness or farsightedness. A special cylindrical lens is placed in the eyeglasses to correct the condition. Presbyopia is a condition that exists when the natural crystalline lens of the eye loses some of its ability to change shape in order to focus on near objects. Typically, people moving beyond the age of 40 eventually develop presbyopia, which is indicated by a need for reading or bifocal eyeglasses. Corrective eyeglasses with convex lenses compensate for these refractive errors.

Eyeglass Care - How to Clean Your Eyeglasses

  • For regular cleaning, use only a microfiber lens cloth (included with your order).

  • Always wet your lenses before cleaning them. Cleaning them when they are dry may cause scratching.

  • When necessary, dip your lenses into warm water and rinse them under running water. Avoid using ammonia based products.

  • Don't polish your lenses, just remove the water.

  • Always take your eyeglasses off with 2 hands. Try not to pull the glasses to one side.

  • When not needed, keep your eyeglasses in their case (included with your order). That will help maintain the scratch resistance of your lenses and overall condition of your glasses.
